What do I do when asked to log into the proxy server within a resource that uses frames?

If authentication becomes necessary while you are working with a resource that uses frames, the login form will be displayed within one of the resource's frames. Generally this is no problem, but sometimes it is displayed in a short or narrow frame where it is hard to read.

You can usually adjust the dimensions of the frame by dragging its boundaries with the mouse. Alternately, you can use your "Tab" key to move from one field to another within that frame.
